Abstract (en)
[origin: WO9852468A2] An X-ray examination apparatus (1) includes an X-ray source (2), an X-ray detector (5) and an X-ray filter (6). The X-ray filter (6) is arranged between the X-ray source and the X-ray detector. The X-ray filter (6) includes a plurality of filter elements (7) whose X-ray absorptivity can be adjusted by adjusting a quantity of X-ray absorbing liquid (30) present in individual filter elements (7). The filter elements are formed by substantially parallel plates (8), respective plates being provided with separating members (10) which project approximately transversely from the plane of such a plate. The filter elements are formed notably by parallel corrugated plates or by parallel plates provided with partitions extending transversely from the plates.
